Publish Page going to Internal Server Error

Hello,

I am trying to publish a page, which will be a static home page. When I go to publish it doesn’t work and gives me an Internal Server Error. I’ve had no problems with publishing any other page but this one. I’ve successfully published it with a line of me swearing. lol So I assume something in the HTML might be the problem. The odd thing is that I have this exact same page set up elsewhere with no issues.

Is this a possibility? The html has a lot of text formatting as I was still learning css when it was created. I can supply the page html if needed.

Thank you.
